Ive been looking at many gm factory wheels coming through the scrap and ive gotten curious if anyone knows what the stampings mean? If i can learn to decipher them. @Keith Seymore maybe??

Date codes and manufacturers markings.

The "JJ" is what is called the broadcast code for that specific part number.

If you have the build sheet it should call out the JJ, telling the guy on the line to use that wheel on that truck.

It's easier to remember JJ than it is a seven or eight digit part number every job.

Here's a Corvette rally for sale, with some discussion about the codes.

I believe my Chevelle came with "AZ" wheels on it.

From what I've gathered, all of the 15x8 Corvette rallies were stamped with the AZ code.

Is that what they really go for? I bought one once for 35 bucks at a swap meet. I still need one more.

It's possible. If there only was one version then there would only be one part number required; each broadcast code is unique to that part number.

If, however, they ever changed anything they wanted to track, like offset, or valve stem hole size, or going from welded to riveted (or whatever), then they would change part numbers and therefore broadcast codes.

The odds of them making some kind of change over several model years and several product lines is pretty high.

I'll check my reserves next time I think of it while I am out back (I have well over 20 Corvette rallys of all different shapes and sizes).

Probably not, not for normal people. Those Yenko guys have money to burn.
